BBR Tuning High Performance F2 Thrust Exhaust Muffler- Black

Fits perfect on my bike, haven't ran it yet, but it looks awesome, unlike the stock exhaust. The design is great. Just what I was looking for. Happy with my purchase!

I knew this was loud when I got it, but I also saw a lot of people with pretty significant gains. If it's that good, I don't care how loud it is. So I installed it and went for a ride. My top end increased by about 3-5mph and I got better mid range power throughout. I couldn't be happier with the performance.I put a fiberglass pipe wrap over the pipe after I burned my leg. The wrap fixed it.Now, the noise... I figured I could put up with any amount of noise. I like loud pipes. But, after installing this, I was literally embarrassed to drive it through town. I was driving down my block, which is basically in the woods, and my neighbors covered their ears.So I basically removed the pipe and it's sitting on my garage floor. I would install it if I was riding through a more rural area or racing, but I am basically too embarrassed to ride it around my neighborhood.

Unlike some people here, the welds on my pipe were in decent condition; no holes through the welds or anything bad like that. The pipe looked like it wasn't going to line up, but the install went smoothly. I recommend using the supplied hardware to make a brace for the rear so you don't end up breaking the block where the pipe meets it, since this pipe is long and puts a lot of torque on those bolts. This pipe is insanely loud, the decibel ratings from bikeberry.com's test don't do it justice. Some of my friends are scared to ride it in public. The performance is better, especially in the midrange, and we were able to squeeze 2mph more than the stock pipe, so from 24 to 26mph. We also installed a new spark plug and tuned the carb via the idle screw to get it to idle, and the e-clip on the needle to get it to optimal conditions. Upon a heavy load, such as going uphill and twisting the throttle a lot, the sound changes from a POP POP POP POP to a weedeater sound. Not sure what exactly that means but it may just have something to the with the shape of the pipe. The sound difference is not gradual either, it's a distinct difference when it makes that sound. ALSO, the pipe shoots the exhaust directly on the rear tire and braking surface of the wheel, so I'm going to buy some rubber or silicone (or metal at a last resort) deflector to shoot it out of the direction of the tire. Lastly, this pipe is a leg burner. I've burnt my thigh on it at least 3 times already, so I'm buying some exhaust wrap to wrap around the pipe to help with the leg burns 4/5 stars, i was expecting more of a performance jump.

Worth the buy!

I purchased the F2 Thrust because the exhaust that came with my engine kit interfered with the fender on my front tire while turning.There is no sound deadening with this exhaust so it is loud. This can be a con or a pro. The metal is thin. Welds look ugly. the flange was warped from too much heat from welding. The weld around the flange was in the way of mounting bolts. Hardware was missing from my package.I had to un-bend the pipe some by hand to fit with my frame. I used a belt sander to flatten the flang and a grinder to remove so of the weld in the way of the bolt holes so that the bolt could tighten. Made a mount from conduit clamps bought from the hardware store.I love the way it flows with the bike frame, but not worth the money with all the flaws. I would not buy this exhaust again or recommend this exhaust to anyone I like. If they get their sh*t together with the quality it might be a decent part.

The media could not be loaded. 40mm holes lined up, no hard ware just a BA pipe in a box. Stay loud and stay alert. The welds were OK, no holes but almost. The exhausted rap helps with vibrashtion and burning your leg.

The month of the words but it is safe to handle An Extremely Loud I am unable to keep it fully connected to the motor due to vibrations and the way it's set up to be bolted down most likely if anything happened if we give the third degree burn on your leg or the muffler runs

Like the way it sounded and fit. What I did not like is having to figure out where to put the hangers
